centos7安装supervisor

方式一: yum 安装

yum install epel-release

yum install supervisor

systemctl enable supervisord # 开机自启动

systemctl start supervisord # 启动supervisord服务

systemctl status supervisord # 查看supervisord服务状态

ps -ef|grep supervisord # 查看是否存在supervisord进程

方式二: apt-get 安装

apt-get install supervisor

操作

systemctl stop supervisord
systemctl start supervisord
systemctl status supervisord
systemctl reload supervisord
systemctl restart supervisord

使用之前

cat /etc/supervisord.conf

在最底部,会看到:

files = supervisord.d/*.ini

这个会调用 supervisord.d 目录下的配置文件。所以我们的配置文件都建在 supervisord.d 下。

使用

vim laravel-worker.ini

[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /alidata/www/binkeke/binkeke.com/artisan queue:work redis --sleep=3 --tries=3
autostart=true
autorestart=true
user=nginx
numprocs=8
redirect_stderr=true
stdout_logfile=/alidata/www/kwva/supervisord/log.txt

stdout_logfile 文件一定要先创建好哈。

php官网:https://php.net/downloads.php

Nginx官网提供了三个类型的版本。

  1. Mainline version:Mainline 是 Nginx 目前主力在做的版本,可以说是开发版
  2. Stable version:最新稳定版,生产环境上建议使用的版本
  3. Legacy versions:遗留的老版本的稳定版

打开下载页面,选择适合的版本(当前最新版本是7.3.4),进入镜像页面。找到对应的镜像地址。进入存储目录,开始下载。

cd /usr/local/src

http://cn2.php.net/distributions/php-7.3.4.tar.gz

tar -xzvf php-7.3.4.tar.gz

先下着。

准备编译环境

yum install curl-devel

yum install  libxml2-devel

yum install  libjpeg-devel

yum install  libpng-devel

yum install freetype-devel

yum install libxslt-devel

libzip 一定要编译安装,否则版本低,安装 php7.3.4 过不了。不过之前安装 nginx 的时候,已经安装过了。没啥问题了。

安装

cd /usr/local/src/php-7.3.4

./configure --prefix=/alidata/service/php \
--with-config-file-path=/alidata/service/php/etc \
--with-config-file-scan-dir=/alidata/service/php/etc/php.d \
--with-fpm-user=www \
--with-fpm-group=www \
--with-curl \
--with-freetype-dir \
--with-gd \
--with-gettext \
--with-iconv-dir \
--with-kerberos \
--with-libdir=lib64 \
--with-libxml-dir \
--with-mysqli \
--with-openssl \
--with-pcre-regex \
--with-pdo-mysql \
--with-pdo-sqlite \
--with-pear \
--with-png-dir \
--with-jpeg-dir \
--with-xmlrpc \
--with-xsl \
--with-zlib \
--with-bz2 \
--with-mhash \
--enable-fpm \
--enable-bcmath \
--enable-libxml \
--enable-inline-optimization \
--enable-mbregex \
--enable-mbstring \
--enable-opcache \
--enable-pcntl \
--enable-shmop \
--enable-soap \
--enable-sockets \
--enable-sysvsem \
--enable-sysvshm \
--enable-xml \
--enable-zip \
--enable-fpm

如果提示:configure: error: Cannot find OpenSSL's libraries, 那是因为没有找到 libssl.so, 我们需要处理下。

find / -name libssl.so

# 输出
# /usr/local/openssl/lib/libssl.so
# 我们建立一个软链接,再配置 php
ln -s /usr/local/openssl/lib/libssl.so /usr/lib

如果还报这个错,估计少了 openssl-devel,用 yum 安装下。

yum install openssl-devel

如果是其他错误,缺少模块,可以用 yum 安装。

直到提示说 Thank you for using PHP,然后。

make && make install

安装完成之后,可以通过命令 make test 检查一下。

检查发现有好几个 bug。

还得修复。

配置环境变量。

在终端中,任意位置都能使用的命令,需要配置环境变量。就如在win下一样。liunx下,只要编辑 /etc/profile 文件并 source 就可以。

vi /etc/profile

在末尾追加

PATH=$PATH:/alidata/service/php/bin
export PATH

保存,然后 source

source /etc/profile
echo $PATH  #看到配置的环境变量了
php -v #查看php的版本信息

刚安装完成,你并不会发现 php-fpm.conf,www.conf 以及 php.ini 文件。这几个重要文件,其实都有,前边两个文件只是将名字后边加了 .default 。第三个文件在源码包的根目录里,而且有两个,一个是 php.ini-development ,另一个是php.ini-production。既然找到了对应文件的位置,只需要复制一份过来就可以了。注意复制过来的路径(-with-config-file-path对应)和名字。

填充文件。

cp /alidata/service/php/etc/php-fpm.conf.default  /alidata/service/php/etc/php-fpm.conf
cp /alidata/service/php/etc/php-fpm.d/www.conf.default /alidata/service/php/etc/php-fpm.d/www.conf

cp /usr/local/src/php-7.3.4/php.ini-production  /alidata/service/php/etc/php.ini

cp /usr/local/src/php-7.3.4/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

chmod +x /etc/init.d/php-fpm

chkconfig --add php-fpm  #开机自启动

开启可以这样

#启动服务
service php-fpm start 
#停止服务
service php-fpm stop  
#重启服务
service php-fpm reload

到此,我们熟悉的 /etc/init.d/php-fpm start回来了。

/etc/init.d/php-fpm start   #开启
/etc/init.d/php-fpm stop  #关闭
/etc/init.d/php-fpm restart  #重启
php -i|grep php.ini

当下 (2019-04-20)最新的稳定版本的 nginx 版本是 1.14.2。下边来进行编译安装该版本,使其支持 http2 以及 TLS1.3 还有 Brotli 。 都是好东西,可以慢慢去了解。

安装依赖包

### 先更新包,软件,系统内核
yum update 

安装 gcc

安装 nginx 源码进行编译,编译依赖 gcc 环境,需要安装gcc: yum install gcc-c++

安装 pcre-devel

PCRE(Perl Compatible Regular Expressions) 是一个Perl库,包括 perl 兼容的正则表达式库。nginx 的 http 模块使用 pcre 来解析正则表达式,所以需要在 linux 上安装 pcre 库,pcre-devel 是使用 pcre 开发的一个二次开发库。

yum install  pcre pcre-devel

zlib 安装

nginx 使用 zlib 对 http 包的内容进行 gzip。可是,不是用 Brotli 么。两个都装,装了也没事。gzip 编译安装来个。如果不编译,使用 yum 安装,版本达不到要求。

# 版本没要求可以这样
yum install zlib zlib-devel

先安装 cmake
https://blog.vini123.com/289

再安装 zlib
https://blog.vini123.com/299

再安装 bzip2
https://blog.vini123.com/300

最后安装 libzib
https://blog.vini123.com/290

OpenSSL 安装

OpenSSL 是一个强大的安全套接字层密码库,囊括主要的密码算法、常用的密钥和证书封装管理功能及 SSL 协议,并提供丰富的应用程序供测试或其它目的使用。

https://blog.vini123.com/301

安装 ngx_brotli

cd /opt
git clone https://github.com/eustas/ngx_brotli.git
cd ngx_brotli
git submodule update --init --recursive

可以看这里: https://blog.vini123.com/302

增加用户组

我们创建一个新的用户组和用户来运行服务,这样可以把nginx和root分开,保证nginx不具备root权限。但是,我们并不希望nginx成为一个真实的可以登陆到远程进行操作的用户,所以,我们并不给它创建home目录,在useradd的时候,用-M参数:

 groupadd www
 useradd -g www -M www

-g参数为nginx用户指定了一个组。-M参数保证其不自动生成home目录。

但通过上面的用户创建之后,www 用户可以通过设置一个密码登陆到服务器,这个不是我们想要的,我们禁用它的 ssh 登陆权限.禁止用户登陆也很方便,只需要修改配置文件中有关用户和用户组的信息即可。

vi /etc/passwd

找到www,将后面的/bin/bash改为/sbin/nologin即可。

下载安装 nginx

官网:http://nginx.org/en/download.html 当前最新稳定版本 1.14.2

cd /usr/local/src

wget http://nginx.org/download/nginx-1.14.2.tar.gz

tar -xzvf nginx-1.14.2.tar.gz

cd nginx-1.14.2 

配置编译

./configure \
--user=www \
--group=www \
--prefix=/alidata/service/nginx \
--pid-path=/alidata/service/nginx/run/nginx.pid \
--with-http_stub_status_module \ ## 监控模块,nginx自带,但默认不安装
--with-threads \
--with-file-aio \
--with-pcre-jit \
--with-http_ssl_module \ ## 开启 HTTPS 支持
--with-http_v2_module \ ## 开启 HTTP/2 
--with-http_gzip_static_module \ ## 开启 GZip 压缩
--with-http_sub_module \
--with-http_flv_module \
--with-http_mp4_module \
--with-http_gunzip_module \
--with-http_realip_module \
--with-http_addition_module \
--with-stream \
--with-stream_ssl_module \
--with-stream_ssl_preread_module \
--with-stream_realip_module \
--with-http_slice_module \
--with-pcre \
--with-openssl=/usr/local/src/openssl-1.1.1b/  \ ## 指定单独编译入 OpenSSL 的源码位置
--with-openssl-opt=enable-tls1_3 \ ## 开启 TLS 1.3 支持
--add-module=/usr/local/src/ngx_brotli/ ## 编译入 ngx_BroTli 扩展

如果有问题,将这些配置写成一行。没有问题会提示:


Configuration summary + using threads + using system PCRE library + using OpenSSL library: /usr/local/src/openssl-1.1.1b + using system zlib library nginx path prefix: "/alidata/service/nginx" nginx binary file: "/alidata/service/nginx/sbin/nginx" nginx modules path: "/alidata/service/nginx/modules" nginx configuration prefix: "/alidata/service/nginx/conf" nginx configuration file: "/alidata/service/nginx/conf/nginx.conf" nginx pid file: "/alidata/service/nginx/run/nginx.pid" nginx error log file: "/alidata/service/nginx/logs/error.log" nginx http access log file: "/alidata/service/nginx/logs/access.log" nginx http client request body temporary files: "client_body_temp" nginx http proxy temporary files: "proxy_temp" nginx http fastcgi temporary files: "fastcgi_temp" nginx http uwsgi temporary files: "uwsgi_temp" nginx http scgi temporary files: "scgi_temp"

好了,现在开始编译安装。

make && make install

安装完毕后,启动 nginx

/alidata/server/nginx/sbin/nginx 
ps -ef|grep nginx

# 查看编译的模块
/alidata/service/nginx/sbin/nginx -V

配置开机自启动

切换到 /lib/systemd/system/ 目录,创建 nginx.service 文件 vi nginx.service
编辑 nginx.service

[Unit]
Description=nginx 
After=network.target 

[Service] 
Type=forking 
ExecStart=/alidata/service/nginx/sbin/nginx
ExecReload=/alidata/service/nginx/sbin/nginx reload
ExecStop=/alidata/service/nginx/sbin/nginx quit
PrivateTmp=true 

[Install] 
WantedBy=multi-user.target

保存,并退出。再执行 systemctl enable nginx.service 激活重启自启动功能

systemctl enable nginx.service

systemctl start nginx.service #启动nginx
systemctl stop nginx.service #结束nginx
systemctl restart nginx.service #重启nginx

curl 127.0.0.1 查看欢迎页面。或输入外网 ip,如果外网 ip 访问不到,可能是 80端口没开放。去开放端口。比如去阿里云添加安全组,再重启 nginx。

https 测试

https://myssl.com

nginx 配置

ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
add_header Strict-Transport-Security "max-age=31536000";
add_header Content-Security-Policy "default-src 'self';script-src * 'unsafe-inline';style-src * 'unsafe-inline';";
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";
add_header X-Frame-Options 'SAMEORIGIN';

TLS 1.3 也渐渐流行。可以自行配置。

linux 执行定时任务的软件很多。如cron、anacron、at和batch,其中cron和anacron用来定期重复执行指令,At和batch则用来在特定时间执行一次性的指令。这里使用 cron来操作定时任务。

假如我们想每个月更新一下yum包。就可以刚好用到 cron 。
